Interactive Brokers Statistics: Key Facts and Numbers for 2024

All the numbers you were looking for about the brokerage, plus some interesting titbits.

Interactive Brokers Statistics

Founded as a one-man market maker firm in 1977, Interactive Brokers (IBKR) has grown to become one of the largest online stock brokerages in the world. Today, the company’s trading platforms are available in 218 countries and territories across every continent and are home to over 2.2 million professional and personal customers, with around 20% more being added every year. 

The brokerage’s success can largely be attributed to its visionary founder, Thomas Peterffy, who arrived in New York in 1965 as a penniless immigrant. Peterffy, who grew up in communist Hungary, defied all odds to become one of the world’s wealthiest individuals by practically inventing digital trading and computers to the trading floors of Wall Street. By 1979, he had a team of four traders working alongside him; today, IBKR boasts nearly 3,000 employees worldwide.

IBKR overview

Interactive Brokers was founded by Thomas Peterffy, an immigrant who fled communist Hungary to New York in 1965. He began his career as a technical drawer at a highway designing firm, where he taught himself computer programming. With this skill, he transitioned to Wall Street, where he worked for Mocatta Metals as a commodity trading software designer.

In 1977, Peterffy had saved enough to buy a seat on the American Stock Exchange to trade equity options under his own name. The year after, in 1978, he founded the company T.P. & Co to employ more traders and expand trading activities. In 1982, it was renamed Timber Hill Inc. and once again Interactive Brokers in 2001. Today, headquartered in Greenwich, Interactive Brokers logs around two million trades per day.
